Why is the Arctic is colder than the equator?

In theory, the Arctic remains colder than the equator because more of the heat from the sun is reflected off the ice, back into space. Glaciers around the world can range from ice that is several hundred to several thousand years old and provide a scientific record of how climate has changed over time.

Explanation:

There are a number of reasons why the Arctic remains cold, even in summer. The primary reason is that the sun is low on the horizon all day. Thus, solar energy needs to pass through more atmosphere to get to the ground. In addition, the high reflectivity (albedo) of snow and ice surfaces means that very little of the energy that reaches the ground stays there. Therefore, the heat gained during the long summer days is small and highly dependent on topography and albedo. For instance, wet tundra and bare ground absorb more solar radiation than ice sheets. Similarly, wet snow absorbs more radiation than dry snow.
